To aZZ whom it may concern:

Be it known that l, FREDERICK (C. @vinn- BURY, a citizen of the United States, residing in Rutherford, county of bergen, and State of New Jersey, have invented certain new and useful improvements in Machines for Making Fab-ric Shingles, of which the following is a specification.V

rFhis invention relates to a machine for making fabric shingles and more particularly to a mechanism for automatically forming shingles of the type in which the exposed edge has a folded portionadapted to underlie the main portion of the shingle and form a securing element thereof.

ln shingles of the character referred to, the lower edge of the shingle is connected to the main portion of the shingle by a bend whidh is formed and set while the fabric and its coating are in a heated or plastic c0ndi=' tion. ln laying these shingles they are secured to the rooting in overlapping courses with the joints broken in the usual manner. However, in place of driving rthe nail or other securing member through the main portion of the shingle it is driven through the return bent lower edge portion; the remainder of the shingle being turned back while the nails are driven and the main portion of the shingle then drawn up over the nailed portion iving a double or thickened edge etlect to t gle. The peculiar manner of securing these shingles to the roofing makes it advisable to provide some means of roperly Iindicating the amount of overlap or each succeeding course and it is among the objects of invention to provide a, means for placing on the under side of the shingle guide marks which, when the shingle is bent over into its attached position, will indicate the correct part of the shingle to which the nailing strip on the next shingle shall be secured.

@ther salient objects of 'dhe invention are to provide a machine by which such shingles can be automatically formed and the bent portion. properly stretched and set a heated condition; to provide a ny chine which will perform both the bending opera tion above described and properly position the holes through which the nails are being driven; 'to provide means for forming the overlap guide marks referably "simultaneouslywith the formation of the nail holes;

will be automatically conveyed to the packing space, the rolls which set the bends being preferably employed for carrying the shinu ples away from the formin mechanism;

' and in general to provide a simple and efiicient mechanism by willich a plain blank can be rapidly and automatically converted into a` Complete shingle having the characteristics above mentioned. resides in various features of construction and combination of parts hereinafter described.

Referring in detail to the particular embodiment of my invention shown in the. drawings, fand describing first the type of shingle manufactured by the machine, l designates the blank formed of flexible fabric coated with a bituminous substance or compound, this blank having a main portion 2, and a securing flap 3, the latter being connected to the main portion by an integral bend 4, which forms the lower or exposed edge of the shingle when laid. rlhe flap portion 3 is provided with nail holes 5. and 5', while on the reverse side of the blank and on the opposite side of the bend 4 is a plurality of guide marks 6 and 7, which indicate the amount of overlap that should be allowed in laying the 'next course of shingies.

For making shingles of the character rll`he invention further lll@ lllli above described, 1 employ a power driven machine 8, which is mounted on a bed plate 9 and has the following mechanical con: struction: 1() designates the feed bed along which the shingle is fed until its inner end reaches the stop 11. 1n Fig. 3 it will be noticed that a pair of side guides 12 and 13 are also employed against which the outer edge of each of the Sides of the' shingle rests, it being understood that a pair of shingles are operated upon simultaneously in the particular machine shown.

When the shingles have been advanced along the feed bed untilthey abut against the stop 11, they are correctlypositioned both laterally and longitudinally relative to the forming mechanism, and the next operation on the blank is the formation of the nail holes and the production of the overlap marks on the under side of the sheet after which the blank is bent and` removed.

All of these operations are performed byl mechanism driven 'from a common driving shaft 14, on which is mounted a large cam wheel 15 having a projecting cam member 16 and an auxiliary cam member 17. The

last mentioned cani member during each revkolution of the shaft operates upon a roller 18 carried by a swinging arm 19, which in turn is non-rotatively secured to a rock shaft 20. Similarly secured to this shaft is a plurality of rock arms 21, eac-h having at its lower vend a hammer member 22, which is positioned directly above but normally spaced from coperating marking members 23.

r1`he construction is such that when the cam 17, acting on the roller 18, rocks the arm 19 and the shaft 20, the hammer members 22 will be forced downward against the upper surface of the shingle and will press the lower face of such blank onto the marking members 23 and thereby form indentations on the under side of the blank, which indentations will serve as guide marks to show the amount of overlap in laying the neXt course of shingles. r1`he shaft 20 carries at one end an arm 24 provided at its free end with a stud for engaging the free end of an arm `25 connected to a rock shaft, which carries companion arms linked at their outer ends to a cross shaft 26 carrying nail hole punches 27.' Thus, as the lever 21 forces the hammer members down against the shingle blank, it simultaneously forces the nail punches 27 downward to perforate the shingle blank sufiiciently to indicate wherethe nails shall be driven. Each of the nail hole punches 27 is provided with a spring 28, which serves to automatically return the punches to their raised position as soon as the action of. the cani member 17 is completed.

JT ust after the overlap and nail hole marks have been produced' on the respective op- 'can be heated in any suitable manner such posite sides of .the sheet, the cam member 16 moves into engagement with the roller 30 on the free end of a rock arm 31:, which is pivoted at 32. This moves the free end of the rock arm 31 upward andr thus forces downward the opposite end of this arm 31, which is connected by a link 33 to the sliding head 34, and carries the dull knife or plunger 35. The ydownward movement of this plunger bends the blank near its inner edge downwardly and carries it into engagement with the rollers 36 and 37, the latterof which' is slidably mounted and spring pressed toward the former by a coil spring 38.

For driving the rollers 36 and 37 they `are provided ,with intermeshing gears 40 and 41, the former of which meshes with an intermediate gear 42, which in turn is driven by a large gear wheel 43 mounted upon the shaft 14. Positioned just beneathv the rollers 36 and 37 is an auxiliary pair of rollers 44 4and 45, the latter being spring pressed toward the roller 44 by the action of a spring 48. These rollers are provided with intermeshing gears 46 and 47, the gear 46 also meshing with the intermediate gear 42. Both sets ofrollers are therefore driven'4 from the same power shaft thatstlie marking and `bending mechanism is operated by, and all the operations are thus positively actuated in proper sequence.

Positioned at one side of the bed plate 9 is a heating tank 50, the water within which as by the heating coil 51. Before placing the shingles on the feed bed, they are placed in the tank 50 where they are subjected to the action of heat and softened so that the plunger 35 in bending the shingle will not break down the liber ofthe fabric or its coatin rlhe shingles after being treated are ta {en from the tank and advanced along the feed bed until their inner ends abut against the stops 11. and shingle nail holes are then produced as above described and the inner ends of the shingle bent and forced downwardly by the action of the plunger l35 until they are forced intermediate the rollers 36 and 37. These l rollers rotating inthe direction indicated by the arrows and being spring pressed together will draw the bent end of each of the shingles between them and carry them down until they reach the auxiliary rollers l 44 and 45, which serve to further press and set the return bend ends or flaps 3 back upon the main portion 2. These last mentioned rollers are also driven in a direction to carry the shingles downward onto the incline 1i rlhe overlap marks l.'

meneer laid with the return bent securing flap po-V sitioned under the main portion of the shingle andwithout danger ofthe shingle cracking at the bend. Moreover, the formation of the overlap guide marks and the nail hole marks enables the shingles to be rapidly and accuratelyA applied to the roof. While l have shoivn and described the machine as adapted to produce a particular type of shingle, it is obvious that the use of the machine is not limited to the specific use mentioned and that various changes in construction and combination of parts canbe made Within the scope of my invention.
